Vandals spray-painted satanic graffiti on four Long Island churches over the weekend, police said Sunday.

The disturbing scrawls — which included the words “hail Satan” as well as pentagrams — appeared on the houses of worship in North Amityville, Suffolk County, sometime between Friday night and Saturday, according to authorities.

“They must have a vendetta,” said Walter Willie, the 62-year-old pastor of the defaced Prayer Tabernacle Church of God in Christ. “To attack a place of healing, a place that helps people in time of great need — whoever did this has hurt in their heart.”

Congregants found similar drawings at the Amityville Full Gospel Tabernacle, Zion Gospel Church and Shaw Temple AME Zion Church, according to police. All of the churches are within a mile of each other.

Pentagrams are used in several pagan religions, but satanists in particular employ the “downward” version — which features two devil-horn-like points facing up — that was found on the Long Island churches, according to Dakota Hendrix, an owner of the Brooklyn occult bookstore Catland.

The churches’ pastors and congregants fired back Sunday, holding a sort of exorcism at their vandalized churches.

“The blood of Jesus covers this house! No distress, no fear, to this family!” shouted Amityville Full Gospel’s pastor, William Walker, 48, as he placed his hands on the doors of Shaw Temple AME Zion Church, where a pentagram had been removed. “Bless this house, no sign of evil will stop the word of God. Hail Jesus, hail Jesus, hail Jesus!”

The Shaw Temple is part of the African Methodist Episcopal tradition, and the other three churches are Pentecostal.

Police are treating the vandalism as a religious hate crime. But they also are investigating whether a disgruntled parishioner may have scrawled the dark messages out of spite, according to Detective Lt. Bob Donohue of the Suffolk County Police Department.

“We are disturbed by this. It is disrespectful,” he said. “I am asking [the pastors] to speak to their parishioners, find out if anyone sees or heard anything on social media.”

Last week, police in Nassau County found demonic imagery and phrases spray-painted on the New Covenant Church in East Meadow, but the upside-down crosses scrawled on that church do not match the graffiti in North Amityville, cops said.

“It is really scary! It is a sign of the end of time coming,” George Richardson, 81, told The Post as he entered Shaw Temple AME for Sunday service.

“It is a shame this is what the world is coming to. We need more prayer.”
